What Is The Best Octane Boost
 

What is The Best Octane Boost, How much & Where to buy From.

How Safe is it to run a Scooby Import without Octane boost, Shoud you use it in every tank.

what kinda scoob??you have optimax on tap over there, this should be good enough for your scoob without octane booster, nf race is good stuff, only add a lil but to each tank, pricey enough but as i said one bottle should last you at least 2 full tanks ;)

Impreza Type RA WRX 2000w Jap Import,

I used to use millers,but have changed to nf due to hearing good reports.Have to say the car runs better on nf than it ever did on millers.

Right then unless your jdm car has been remapped for uk spec fuels it's best you stick with a good quality fuel and a booster for piece of mind.
Lets say Shells Optimax and a quality booster. Many to choose from here but at the moment i'm favouring Nitrous formula
At about £14 a bottle its not cheep however one bootle will do about 6 tank fulls (Black Race Formula) 50ml per tank is all that is required. So in the long run it works out cheeper than say Millers booster at £3.50 per bootle or there abouts and thats a 1 bottle 1 tank exercise.
